UNITED ST Application filed May 1e,

The successful filing of saws by hand is both a tedious and time consuming operation even to those skilled in this particular art. As a matter-of-fact, it is almost imposible to file all of the teeth of a saw so that the cutting edges thereof will be in the same straight line and to hold the file so that :all of the teeth will be at the same angular pitch, as the successive movement'of the file f in the operation upon the different teeth'of the saw Will naturally cause a slight canting or tilting of thesaw as well as the. dis "arrangement'of the angular plane at which the file is I'eciprocate d. It may, therefore, be considered the primary object of this in vention to provide means whereby "the file will be held at the sameiangleforevery tooth filed and the saw guided at the same angle when reciprocatedbetween the several teeth of the saw during the filing operation. To this end I'aim to provide a removable gauge plate for the saw clamp that has a horizontal surface inscribed thereon with flines'o'f inclination at which thefileis to be I there being friction means between the plate with the plate.

and the file holding member for'preventing the free turning of either the plate or the member, the saidfriction means also hold- 'ing the pointer in contacting engagement To-the attainment of the above broadly stated objects and others which-will present themselves as the nature of the invention is better understood, the invention resides in certainother novel features of construction, combination'and operative. association of parts, a satisfactory embodiment of which is disclosed by the accompanying drawings:
